Alloreactive T-cell recognition of two DQ beta allelic specificities associated with DQw1
Two sets of alloreactive T-cell clones from different original mixed lymphocyte reactions (MLR) discriminate between two DQ beta allelic forms when these are expressed in association with the same DQ alpha form. From these results we concluded that it is possible to guide a DQ specific response of alloreactive T-cell clones by setting up an appropriate responder-stimulator combination in the original MLR; DQw1 is associated with two allelic forms of the DQ molecule recognized as lymphocyte activating determinants by alloreactive T-cell clones; alloreactive T cells recognize specific alpha-beta chain combination of the DQ molecule; the allelic forms that differentiate the alpha or the beta chains of the DQ molecule from each other can also be recognized at the molecular level by DQ alpha and DQ beta RFLP analysis.
